In this work the water quality of private wells in the area of the City of Lipik was determined using microbiological and physicochemical indicators. Four water samples were collected and tested in the ecological laboratory of the Institute of Public Health in Požega. The purpose of this paper is to examine and determine the health and water quality of private wells and to use indicators to determine whether the results meet the recommended MDK values. The following microbiological parameters were determined: total coliform bacteria, Escherichia coli, enterococci, total number of colonies at 22 ° C and total number of colonies at 36 ° C. From the physico chemical parameters were determined: color, turbidity, electrical conductivity, odor, taste, temperature, concentration of hydrogen ions, consumption of potassium permanganate, chlorides, nitrates, nitrites, ammonia, total water hardness and total iron, manganese and aluminum. From the obtained results it can be concluded that the samples exceed the recommended MDK values and for this reason the water of all samples taken is considered defective and unacceptable for consumption.
